With filming set to begin later this month, some of the final pieces of casting for the film X-Men: First Class are falling into place. Joining the recently announced Rose Byrne and Jason Flemyng, Oliver Platt is the newest addition to the start studded cast.

Along with James McAvoy as Xavier, Michael Fassbender as Magneto, Alice Eve as Emma Frost, Nicholas Hoult as Beast, Jennifer Lawrence as Mystique, Caleb Landry Jones as Banshee, Lucas Till as Havoc, Edi Gathegi as Darwin, Kevin Bacon as the villain, Jason Flemyng as Azazel and Rose Byrne as Moira MacTaggert, we now have Oliver Platt joining as “The Man in Black”.

Like Kevin Bacon before him, Oliver Platt’s character has yet to be described fully. So far the only information being released is that Platt will not be playing a mutant character.

Even though I feel that I’m versed in the world of geekdom and comics, I’m not sure who this “Man in Black” character could be. If he was a mutant, many names come to mind ranging from Black Tom Cassidy to the Black Rook of the Hellfire Club. The moniker may just be a blanket government agent title.

There are still some glaring absences in the list of parts that have been cast. If this film is to mirror the comics at all, we are still missing Cyclops, Jean Grey, Angel and Iceman.

Who do you think Platt will play? Who do you think will play the remaining major parts?
